How can I declare a table without primary key? - mysql

Question

I am using MySQL Query Browser.
I have tried this code:
CREATE TABLE `something`.`payment_something` (
`firstName` varchar(15) NOT NULL,
`lastName` varchar(15) NOT NULL,
`inputEmail` varchar(55) NOT NULL,
`genderRadios` varchar(15) NOT NULL,
`monthh` varchar(10) NOT NULL,
`dayy` varchar(10) NOT NULL,
`yearr` varchar(10) NOT NULL,
`postalAddress` varchar(15) NOT NULL,
`phoneNumber` varchar(15) NOT NULL,
`ZipCode` varchar(15) NOT NULL,
`CreditCard` varchar(15) NOT NULL,
`expireMonth` varchar(10) NOT NULL,
`expireYear` varchar(10) NOT NULL,
`Institution` varchar(25) NOT NULL,
`textinput` varchar(15) NOT NULL,
`radios` varchar(10) NOT NULL,
PRIMARY KEY ()
) ENGINE=InnoDB DEFAULT CHARSET=greek;
of course it shows error in the PRIMARY KEY line. Any idea?
EDIT Better solution
CREATE TABLE `something`.`payment_something` (
`id` int(15) NOT NULL AUTO_INCREMENT,
`firstName` varchar(15) NOT NULL,
`lastName` varchar(15) NOT NULL,
`inputEmail` varchar(55) NOT NULL,
`genderRadios` varchar(15) NOT NULL,
`monthh` varchar(10) NOT NULL,
`dayy` varchar(10) NOT NULL,
`yearr` varchar(10) NOT NULL,
`postalAddress` varchar(15) NOT NULL,
`phoneNumber` varchar(15) NOT NULL,
`ZipCode` varchar(15) NOT NULL,
`CreditCard` varchar(15) NOT NULL,
`expireMonth` varchar(10) NOT NULL,
`expireYear` varchar(10) NOT NULL,
`Institution` varchar(25) NOT NULL,
`textinput` varchar(15) NOT NULL,
`radios` varchar(10) NOT NULL,
PRIMARY KEY ('id')
) ENGINE=InnoDB DEFAULT CHARSET=greek;
It shows wrong in the PRIMARY KEY line why?

Answer 1

Simply exclude the problematic line:
PRIMARY KEY ()
You don't need to have that line, if you are not actually defining a key. In your example, you will also have to remove the comma directly preceding this line, of course.
UPDATE:
In your updated example, just take the '' off of 'id' when you declare it. Use the backtick (`), instead of the apostrophe:
PRIMARY KEY (`id`)
